(NBC News) For nearly a decade, a band of cybercriminals rampaged through the servers of a global business who’s who: Among the victims were 7-Eleven, Dow Jones, Nasdaq, JetBlue and JC Penney. Prosecutors say the hackers stole “conservatively” 160 million credit card numbers, and the dollar value of the crimes they helped facilitate is enormous — just four of the victims are out $300 million. The suffering caused to identity theft victims was “immeasurable,” say prosecutors.

On Thursday, five of the gang’s members were indicted. One is in custody in the U.S., a second is awaiting extradition in the Netherlands, and three more are still at large in what U.S. Attorney Paul Fishman said is the largest data heist case ever prosecuted.
